Hostile Desires (Task Force Hawaii, #2) by Melissa Schroeder

As a cold case heats up, two former adversaries discover there is a thin line between love and hate.

TASK FORCE HAWAII, BOOK TWO

Seven years ago, Dr. Elle Middleton’s world crashed and burned. She has rebuilt her life and found comfort in her work as the medical examiner for TFH. When a new case leads to a cold case, she is beyond excited for the challenge, until she finds out the one man she wants to avoid is her partner on the case.

Graeme McGregor isn’t any happier with the assignment. The doctor gets under his skin in more ways than one. He’s avoided her and his attraction by keeping his distance from her, but working with her has made it impossible to resist taking a little taste.

One kiss leads to another…then to a full blown affair. But even as they draw closer to each other, secrets from that long ago murder rise to the surface. The killer’s determination to stay free leads to a dangerous confrontation that puts both of their lives in peril and could leave TFH in shambles
